Proxy Server Samsung

When parsing RSS feeds and avoiding duplicates, you typically need to maintain a record of previously parsed items and compare new items to this record to ensure that you don't process the same item multiple times. Below is an example using Node.js and the rss-parser library, which simplifies working with RSS feeds.

Install Dependencies

Install the required npm package:

npm install rss-parser

Write the Parsing Script

Create a Node.js script (e.g., parse_rss.js) with the following code:

const Parser = require('rss-parser');
const fs = require('fs');

const parser = new Parser();
const rssFeedUrl = 'https://example.com/rss-feed'; // Replace with the URL of the RSS feed

// Function to load and parse the previously processed items
function loadProcessedItems() {
    try {
        const data = fs.readFileSync('processedItems.json');
        return JSON.parse(data);
    } catch (error) {
        return [];
    }
}

// Function to save the processed items to a file
function saveProcessedItems(processedItems) {
    fs.writeFileSync('processedItems.json', JSON.stringify(processedItems, null, 2));
}

async function parseRSS() {
    const processedItems = loadProcessedItems();
    const feed = await parser.parseURL(rssFeedUrl);

    for (const item of feed.items) {
        // Check if the item has been processed before
        if (!processedItems.includes(item.link)) {
            // Process the new item (replace with your processing logic)
            console.log('New item found:', item.title);

            // Add the item link to the list of processed items
            processedItems.push(item.link);
        }
    }

    // Save the updated list of processed items
    saveProcessedItems(processedItems);
}

// Run the RSS parsing process
parseRSS();

Replace 'https://example.com/rss-feed' with the URL of the RSS feed you want to parse.

Run the Script

Run the script using Node.js:

node parse_rss.js

This script uses the rss-parser library to fetch and parse an RSS feed. It maintains a list of processed item links in a JSON file (processedItems.json). Each time the script runs, it loads the processed items, compares them to the new items in the feed, processes only the new items, and then updates the list of processed items.

After authorization in Selenium, you can navigate to another page using the get() method. The following steps outline the process:

Here's an example using Python:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Chrome()
driver.get("https://www.example.com/login")

# Locate the username field, password field, and login button
username_field = driver.find_element(By.ID, "username")
password_field = driver.find_element(By.ID, "password")
login_button = driver.find_element(By.ID, "login-button")

# Input your username and password
username_field.send_keys("your_username")
password_field.send_keys("your_password")

# Click the login button
login_button.click()

# Wait for the page to load after authorization
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "post-login-button")))

# Navigate to another page
driver.get("https://www.example.com/new-page")

In this example, replace "https://www.example.com/login", "username", "password", "login-button", and "your_username", "your_password" with the actual values for the website you are working with. Also, replace "https://www.example.com/new-page" with the URL of the page you want to navigate to after authorization.

Note that the example uses explicit waits to wait for the page to load after authorization. This is a good practice to ensure that the next actions are performed only after the page is fully loaded.

To get a token from local storage, you can use the JavaScript localStorage object, which allows you to store key-value pairs in the browser's local storage. Here's how to get a token from local storage:

Access the token: You can access the token stored in local storage by using the localStorage.getItem() method. This method takes a key as an argument and returns the value associated with that key.

For example, if you have stored a token with the key "authToken", you can retrieve it like this:

const token = localStorage.getItem("authToken");

Use the token: Once you have the token, you can use it in your application as needed. For example, you can include it in the Authorization header of your API requests:

const headers = {
  "Authorization": `Bearer ${token}`,
  // other headers...
};

Remember that local storage is limited to string values, so if your token is an object or has special characters, you might need to encode or serialize it before storing it and then decode or deserialize it when retrieving it.

In e-mail, proxy servers are used for secure data exchange as well as for collecting e-mails from several e-mail addresses at once. For example, this is how Gmail works, which also allows you to receive e-mails from mail.ru and other e-mail services.

Shared proxies should be understood as IPs and port numbers available to everyone. That is, many users can use them simultaneously. The most unreliable and slowest option.
